Do you use PokerTracker or Holdem Manager? This would make it very easy. If not where do you get this hand history from? Like can you copy this in an other format? There are converters online but I'm not sure they will recognize hands copied like this.

You can get more information about how to convert a hand in this article.

It actually is possible for you to put up images of the suits in your hand histories. When making a post, you can see them to the left with the other smilies. The easiest way to put them in though is by using these shortcuts (without the spaces):

: s for
: c for
: h for
: d for

Is that what you're looking for?

Also, there are a lot of hand converters out there. Are you sure that are no hand converters that support the site you're playing on?
